resistance of a fuse

2.51 The resistive elements of fuses, lightbulbs, heaters, etc., are significantly nonlinear (i.e., the resistance is dependent on the current through the element). Assume the resistance of a fuse (Figure P2.51) is given by the expression R = R0[1 + A(T − T0)] with

T − T0 = kP; T0 = 25◦C; A = 0.7[◦C]−1;

k = 0.35◦C/W; R0 = 0.11 Q; and P is the power dissipated in the resistive element of the fuse.

Determine the rated current at which the circuit will melt and open, that is, “blow.” (Hint: The fuse blows when R becomes infinite.)
